Title: G Samuel Hurst: Innovator in Neutron Dosimetry
Introduction
G Samuel Hurst is a notable inventor based in Oak Ridge, TN (US). He has made significant contributions to the field of neutron dosimetry, holding a total of 3 patents. His work focuses on developing advanced methods for measuring neutron doses, which are crucial for various applications in radiation safety.
Latest Patents
One of Hurst's latest patents is a neutron dosimeter that incorporates innovative techniques for determining neutron dose. This dosimeter can measure less than one millirad of dose due to neutrons of all energies down to approximately 10.sup.3 eV. The design allows for adjustments in response, utilizing the sputtering of material from a target due to neutron action. The amount of sputtered material is measured to determine the dose, with potential target materials including noble gases or inert solids. The dosimeter's sensitivity is enhanced by including various radiator materials that interact with neutrons, thereby increasing the sensitivity of the measurement process.
Another significant patent is for sputter-initiated resonance ionization spectrometry. This apparatus and method enable the quantitative analysis of specific species within a sample, achieving sufficient sensitivity to detect as little as one atom of the desired species. The method involves bombarding a sample with a focused charged particle beam, creating a cloud of secondary ions and neutral particles. A laser beam is then used for the unique ionization of the desired species through resonance ionization spectroscopy. This process may include energy and mass discrimination to refine the analysis further.
